Antec Atom V550 V2 SMPS

The Antec Atom V550 V2 is a 550-watt non-modular ATX power supply designed for mainstream desktop PC builds that demand dependable, stable power delivery. Built to comply with the Intel ATX12V 2.31 standard, it integrates smoothly with a wide range of modern motherboards and system configurations. At the heart of its thermal management is a 120mm silent fan coupled with Antec's Thermal Manager — an advanced fan control system that modulates fan speed based on internal temperature and load, keeping acoustics low during light workloads while ramping up airflow when needed. This balance of quiet operation and effective cooling makes the V550 V2 a practical choice for everyday computing and entry-level gaming rigs alike. Circuit reliability is addressed through a comprehensive protection suite: Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP), and No Load Operation (NLO) protection are all built in. These safeguards help protect connected components from potential electrical faults. Being fully non-modular, all cables are permanently attached, which simplifies installation in larger cases where cable routing flexibility is less of a concern. The connector set is generous enough to support a modern mid-range build, including PCIe power for a discrete graphics card. Antec backs this unit with a 2-year manufacturer warranty. --- Verified Specifications --- Model: ATOM V550 V2 Series: Atom Series Form Factor: ATX 12V 2.31 Max.
